MAGNETIC PEEL.

Application led September 26, 1923.

To @ZZ y10i/tom t may concern.'

IBe it known that I, PAUL F. KENNEDY, a citizen of the United States, residing at Marion, in the county of Marion and State of Ohio, have invented new and useful Improvements in Magnetic Ieels, of which the following is a specification.

This invention relates to hoisting devices, particularly those of the magnetic type, and has for its object the. provision of a magnetic peel designed to be 'used in connection with a regulation charging machine used to charge raw material into an open hearth furnace. It is well known that the ordinary method of charging such furnaces is to use a small charging car which is lilled with miscellaneous pieces of scrap. Another method is for the workman to place large pieces of scrap on a flat peel by hand. These old methods are awkward and are slow, tedious and unsatisfactory.

lVith the above facts in view I have designed the present device which eliminates all this unnecessary work and accomplishes the same result in a very short time. Ordinarily charging machines are electrically operated and as a consequence power is handy for the energization of the magnet used in connection with my device.

An important object is the provision of a magnetic pee-l which will be simple and inexpensive in manufacture, highly efcient in use, positive in action7 etlicient and dura.- ble in service and a general improvement in the art.

lith the above and other objects and advantages in. view the invention consists in the details of construction to be hereinafter more fully described and claimed and illustrated in the accompanying' drawings, in which:

Figure 1 is a side elevation of the device showing it mounted upon a portion of 4a charging machine,

Figure 2 is a plan view and Figures 3 and 4 are detail views showing the connection of the head with the charging machine.

In carrying out my invention I provide a main 'body l0 which may be formed preferably as a single casting and which includes an elongated arm 11 and a depending shank 12 which is relatively wide and which has its side edges formed with retaining flanges 13. This shank is also formed with a hole 14.

serial No. 665,030.

Mounted upon the free end of the arm portion 1l is an electromagnet 15 of suitable size and shape and having any necessary winding depending upon the strength of the current to be used and to a certain eX- tent upon the probable weight of the scraps to beY handlec. This magnet is shown as held in position by having its core 16 provided with a reduced extension 17 passing through the arm 1l land carrying a nut 18. The feed cables for supplying current to the magnet are indicated by the numerals 19 and 20 and are housed within a conduit 21 mounted upon one side of the arm 11 and held by brackets or clips 22.

A portion of the charging machine is indicated by the letter A and las is well known this arm or head of the charging machine carries a plate B, through which projects a retractable plunger C.

In mounting my peel, the socket portion or shank 12 is engaged upon the plate B while the plunger C is retracted. When the parts are in such position that the hole 14- in the shank or socket registers with the plunger C, the plunger is extended so as to enter this hole which results in locking the peel iirmly upon the charging machine.

It is of course obvious that when current is supplied to the magnet by closing the circuit through any suitable switch not shown, the magnet will attract and pick up iron scraps of any kind so that they may be readily dropped into the furnace when the switch is opened to break the circuit. The device is very simple and inexpensive and easy to operate so that it sho-uld recommend itself to those havingoccasion to employ :its services. As the parts are so few it is apparent that there is nothing to get out of order so that the device should have a long life and satisfactorily perform all of its functions.

While I have` shown and described the preferred embodiment of my invention it is of course to be understood that I reserve the right to make such changes in the. form, construction and arrangement of parts as will not depart from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention I claim:

1. In combination with a charging' ma* chine, a magnetic peel comprising an elongated arm caiuying an electroma-gnet7 the charging machine hav-ing a plate and a plunger projectalole therethrough, said arm terminating at one end in a Vertical socket engaging upon Said plate and formed With a hole .receiving said plunger.

. 2. In combination with a charging inachine, a magnetic peel comprising an elongated arm, an electromagnet mounted upon one end thereof, a depending shank on the other end of said erm formed with retaining iin-nges and formed with :i holeiy the charging machine carrying n plate having n plunger projectuble therethrough, said plate being received between the flanges on said shank and said hole receiving Suid plunger.

In testimony whereof I :illix my signuture.

PAUL F. KENNEDY.
